Ways to improve the thermal efficiency of coke ovens
Thread Content
(1) Adopt the lowest center temperature of the coke cake while ensuring the quality of the coke； (2) Reduce the temperature in the furnace roof area ； (3) Reduce the moisture content of the coal fed into the furnace ； (4) Select an appropriate a value ； (5) Reduce the temperature of exhaust gas emissions ； (6) Improve the thermal insulation and airtightness of the furnace body ； (7) Reduce the time required for taking the product out of the furnace.
Controlling the gas flow on both sides of the coke discharge port in advance is also a method
Upstairs, how did you manage to do that? The workload associated with adjusting the fire intensity increased quite a bit, didn’t it? The theory is fine, but practical application is quite difficult
This technology already exists today: it enables fully automatic control of gas flow, supplying different amounts of gas depending on the various coking phases, and it has been put into use in production
A simple optimization design calculation can be carried out.
OP: What you say makes a lot of sense, but it’s not that easy to put into practice – for example, how to reduce the temperature in the space above the furnace? How to reduce the moisture content of coal fed into the furnace? Moisture adjustment of coal or coal preheating? Doesn’t this increase equipment and power consumption as well? How to reduce the temperature of exhaust gas emissions, etc. I find it difficult to do this even; could you provide a detailed explanation?
